Abstract
Multiple upset, cold pressure, welding apparatus including (Fig.2) a welding die set having two pairs of die halves each formed with a longitudinal groove in a split line face providing a bore for effecting gripping of end portions of first and second workpiece and reciprocable between the closed position in which the associated portion of the workpiece is gripped and an open position in which the associated portion of the workpiece is released and also being reciprocable in a direction parallel to the longitudinal axis of the workpiece to apply or relax a welding pressure across abutting faces of the end portions of the workpieces, each die being formed witha longitudinal groove having outwardly diverging flanks terminating in a linear knife edge bounding a recess extending longitudinally parallel to the groove in the split line face of the die.
Description
Technical field
The present invention relates to a kind of be used for wire rod, bar, band or tubular workpiece effectively butt welding multiple upsetting, cold pressing, the equipment of smithwelding.
Background technology
WO96/39272 has illustrated a kind of multiple upsetting, has colded pressing, the equipment of smithwelding, and it comprises a smithwelding set of molds with two pairs of mold halfs, and half and half body is formed with a cannelure along die joint.Each cannelure forms a hole at each detent position to mold half, this hole is used for realizing can docking between detent position and the open position clamping of latter end of first and second workpiece of (reciprocable), relevant latter end at the detent position workpiece is clamped and released at the relevant latter end of open position workpiece, and can be along being parallel to workpiece longitudinal axis direction butt joint (reciprocable) to apply or to loosen the smithwelding pressure of the butt joint end face (abutting faces) transverse to each workpiece latter end.
Summary of the invention
According to the present invention, each mould forms the die joint with a cannelure, this cannelure is equivalent to the contour shape of workpiece half section substantially and has the side of the rectilinear edge of termination separately that extends out, and this rectilinear edge defines the recess of the groove extension that longitudinally is parallel in the mould die joint.
Description of drawings
Further specify the present invention by means of accompanying drawing below.In the accompanying drawing:
The drawing in side sectional elevation of the set of molds of Fig. 1 before smithwelding;
The drawing in side sectional elevation of the set of molds of Fig. 2 when smithwelding;
Fig. 3 has the front view of the smithwelding set of molds of two pairs of mold halfs.
The specific embodiment
In one embodiment of the invention, shown in Fig. 1,2 and 3, a pair of mold half 2 is formed with the groove 4 of part circular cross section, and it has a shearing knife edge 6 from planar transfer one-tenth, and this plane comprises the die joint 8 of each halfbody 2.Be provided with recess 10 in the outside of shearing knife edge 6, this recess 10 extends along the total length of the mold half that is parallel to groove 4.
In operating process, the latter end 12 of first and second workpiece be contained in each in the mold half 2 and apply clamping force impel each relevant halfbody mutually to position as shown in Figure 2 with each die joint 8 butt joint (abutting).This latter end 12 is clamped in the groove 4 and comes from latter end 12 is the burr 14 that enter in the recess 10 with respect to the material deformation of groove 4 overdimensioned any surpluses.Each promotes to begin to cold pressing the smithwelding operation mutually to mold half 2 then.
Because the material deformation of any surplus is burr 14, the workpiece that has over dimensioning or lopsided shape latter end 12 can be clamped in the groove 4 under the situation that does not hinder clamping effect or the sudden forces that generation is not difficult to accept on mold half.Thereby, in the available up to now bigger tolerance range scope of the ratio of workpiece size, obtain a kind of clamping effect of satisfaction, thereby improve the versatility of set of molds aspect accommodable workpiece scope.
In another unshowned embodiment, shearing knife edge 6 is set in place in the plane of die joint 8, makes it when realizing clamping, and shearing knife edge 6 cuts off burr, gets rid of burr then when mold half 2 separates.
Should be appreciated that recess 10 can have and is different from the cross section shown in Fig. 1 and 2, for example is semicircle.
Claims (2)
